ejbdeploy tool

I've got WSAD installed on a Redhat 8 box and I'm using the ejbdeploy.sh script (located in /opt/IBM/WebSphereStudio/ApplicationDeveloper/v5.1/runtimes/aes_v4/bin) to generate ejb code for WAS4 app server.I'm running ejbdeploy.sh from the command line , passing all the necessary arguments ,such as the jar file for which I want deploy code to be generated.I wanna stop the deploy tool from generating it's own Schema.dbxmi and Map.mapxmi files , and use pre-existing one that I generated using WSAD.Right now the ones it generates have incorrect table names in the Map.mapxmi file and thus my persistence ejbs are failing to run because ot the wrong table names(I get the Table does not exist messages Any ideas?
